WASHINGTON – An 18-year-old student shot and killed Tuesday evening is the second from Suitland High School in roughly 24 hours and the sixth student lost to gun violence in Prince George’s County in the last six months.

The freshman was found with another man, also 18, in Forestville, Md., at about 5:30 p.m. Both were shot and the other remains in grave condition. Their names have not been released.

In a statement, Brian K. Coleman, spokesperson for Prince George’s County Public Schools, said:

“We are horrified to learn that tragedy struck another one of our students within a 24-hour time-span. Our hearts are broken again and we extend our deepest sympathy and condolences to the family. We cannot go another day without addressing these unspeakable acts of violence against our students. We are asking for the community’s support as our students, teachers and employees cope with these incidents.”

A 15-year-old who attended Suitland High School was shot and killed Monday.

Police found Charles Michael Walker Jr. on the ground and with a gunshot wound in the 4100 block of 28th Avenue in Hillcrest Heights Monday afternoon. The teen — who lived in the 4200 block of 28th Avenue in Hillcrest Heights — was taken to a local hospital and later pronounced dead.

“It’s just crazy,” says one of the victim’s classmates at Suitland. “Why would you pull the trigger on someone who’s not messing with you?”

“That makes me frightened for my life.”

Police say the motive in Walker’s killing was robbery involving a pair of shoes the victim was carrying in a shopping bag. The shoes — sources say they were Timberland boots — were left at the scene of the shooting.

“I am really enraged that a young person in our community can’t walk the streets with a shopping bag without being shot in the back,” Prince George’s County State’s Attorney Angela Alsobrooks says.

Walker was the fifth student who had attended a school in the county to be killed this school year. Tuesday night’s death makes six.

A WTOP review shows other county students killed are:

Amber Stanley, 17, was shot and killed in her own bed. She attended Charles H. Flowers High School.

Marckel Ross, 18, was shot and killed while on his way to school. He attended Central High School.

Marcus Jones, 16, was shot and killed after a weekend house party. He attended Friendly High School.

Eliezer Reyes, 14, was killed in a drive-by shooting. The Gazette reports he had attended Nicholas Orem Middle School, but had switched recently to Foundations School in Largo — an independent school for students with emotional and behavioral disabilities.

Police had made arrests in at least two of the cases — Jones’ and Reyes’ — and were seeking an additional suspect in each. Before the sixth shooting death occurred, ABC7 reported that police expect to make arrests in four of the cases by next week’s end.

Grief counselors were on hand at Suitland High School Tuesday for students, teachers and staff.

Police say detectives have received multiple tips in Walker’s case, and anyone with information on the murder can contact the Prince George’s County Police Department’s Homicide Unit at 301-772-4925.

“We’re just looking for any tips, if there were any witnesses or anyone that saw anything suspicious to please notify us,” Cpl. Larry Johnson with Prince George’s County police tells WTOP.

Baker, whose three children attended Suitland High School, says the county needs to take a comprehensive look at the problems young people are having.

“We need to do more. We can’t arrest our way out of these problems. We can’t prosecute our way out of them,” Baker says.

“These are our young people killing each other, looking each other in the face and shooting at each other, and we’ve got to do something about that,” he says.

Baker, who started the Transforming Neighborhoods Initiative last year, says a holistic approach is needed to preventing violence and helping children. That approach would include schools, police, prosecutors and other agencies focusing on individual neighborhoods.

“We need more intimate involvement in what’s going on in the homelife of these individuals,” Baker says.
